IPC: C01G30/00
Filed: 1985-03-28
Abstract: PURPOSE:To produce granular antimony trioxide suitable as a dopant for semiconductive silicon, easily, by heating and melting antimony trioxide in an inert gas atmosphere under a specific heating condition, and shotting the molten antimony trioxide into water. CONSTITUTION:Powder of antimony trioxide put into a crucible, etc., is placed in a furnace, heated at a heating rate of <=50 deg.C/min in an inert gas stream flowing at a flow rate of 200-1,000cc/min and melted at <=750 deg.C. The molten antimony trioxide is granulated by shotting into water to obtain a granular antimony trioxide free from discoloration and having a particle diameter of about 1-3mm and high commercial value. The shotting is carried out e.g. by filling the molten antimony trioxide in a shotting nozzle having a small die of about 1mm in diameter, and extruding through the die into water in the atmosphere of an inert gas such as helium, argon, etc.

Filed: 1990-03-13
Abstract: PURPOSE:To prevent the generation of the untreated remainder in the terminal treatment of coil winding by changing the cylindrical tip configuration of a nozzle for a coil winding machine into a quadrangle or a triangle. CONSTITUTION:The tip configuration of a nozzle for a coil winding machine is formed into a triangle or a quadrangle, and an edge part is drawn to the terminal treatment part of coil winding to perform travel cutting. The stress of a joint wire is thereby applied to the edge part of the nozzle, so that cutting is performed positively at the edge parts, and thus the generation of the untreated remainder (the uncut remainder of the lead wire) can be prevented.
Patent JP-S50155105-A (JP)
IPC: G10L15/00
Filed: 1974-06-04
Abstract: Speech recognition in prior art uses one extracted characteristic component (xi) to represent one phoneme (Xi) as spoken by one speaker. This invention provides for recognizing the same phoneme as spoken by different speakers, by deriving a group of such components (xik), each a slight variant of the others, to allow finding one component most similar to both the specific phoneme and specific speaker, the method comprising the steps of: normalizing the sound pressure level of an input speech from an unknown speaker; analyzing the normalized voice in a plurality of channels having different frequencies; setting, with respect to the output Fj of each frequency band thus analyzed, a weight  alpha j of the output Fj so that weight alpha j corresponds to a characteristic of a predetermined phoneme Xi; extracting the characteristic component xi of the phoneme Xi, setting a weight  beta j of output Fj so that, when the extracted characteristic component xi causes a malfunction or error due to another phoneme Xe, a characteristic of phoneme Xe is corresponded to; simultaneously extracting the characteristic component xe of phoneme Xe and, when the difference between the characteristic components thus extracted is greater than a predetermined threshold value  gamma i, applying the difference as a characteristic parameter for the phoneme xi; expanding the characteristic parameter to obtain a characteristic parameter group based on the characteristic parameter, each being slightly different from each other so as to be adapted for individual characteristics of different speakers; subsequently extracting from the characteristic parameter group a characteristic parameter, having maximum similarity to a reference parameter previously memorized, as an adaptive parameter adaptive to the unknown speaker; and, matching a standard pattern derived from the extracted adaptive parameters with an unknown pattern corresponding to the unknown speakers, thereby effecting recognition or analysis of the voice.

Abstract: PURPOSE:To improve the dimensional accuracy of a pipe by obtaining the rolling torque of the motor to drive a finished pipe roll rotatively and by controlling the aperture of the finished pipe roll to accord with the torque pattern set previously. CONSTITUTION:The rolling torque of the reeler motor M1 is computed through a speed detector 5 and a torque computing element 6.

The torque pattern has been inputted previously into a torque pattern setter 2 theoretically and experimentally. The rolling torque is computed through the computing element 6 to accord with the previously set torque pattern, to control the aperture of the finished pipe roll. The finished pipe may be controlled at low speed at the end part of the pipe material and at high speed at the central part, further, the detection between the set value and actual value of the torques may be controlled in the allowable range. By this method, the dimensional accuracy of the pipe is improved.

Abstract: PURPOSE: To accomplish an efficient work in a shorter time with a less piston stroke by unifying two pistons with skirt sections of large-and small-diameter cylinders opposed to each other.  
     CONSTITUTION: Pistons 3 and 4 large and small in diameter respectively are so soldly made up in cylinders 1 and 2 large and small in diameter as to be inserted sliding therein with such an arrangement that the large-diameter cylinder 1 and piston 3 form an air buffer chamber 7 and the small-diameter cylinder 2 and piston 4, a combustion chamber 8.

Filed: 1988-03-18
Abstract: PURPOSE:To improve the integrity and reduce the manufacturing cost by a method wherein the width of an element isolation trench is made to be wider in accordance with the depth from the surface of a wafer to be offered for element formation. CONSTITUTION:A semiconductor substrate has, for instance, a single crystal silicon wafer 11 which is used for element formation and has a face orientation of (100) and a single crystal silicon wafer 15 used as a supporter. The two wafers 11 and 15 are unified with an insulating film (for instance a nitride film) 16 between. V-shape element isolation trenches 14 which reach the wafer separating insulating film 16 are formed from the surface of the element forming region of the wafer 11. The side surfaces of the trenches 14 are also covered with the insulating film 16. The trenches 14 are formed in the adhering surface of the wafer 11 before the two wafers 11 and 15 are unified. The width of the trench 14 can be widened in accordance with the depth from the surface of the substrate. With this constitution, the area of the opening of the trench 14 at the substrate surface can be small so that the effective area for the element can be wider. Moreover, single crystal silicon 19 may be grown selectively in the trenches 14 only, so that a final polishing process can be eliminated.
